Thoroughly tested by an independent laboratory, Tubelite’s 400TU Series curtainwall demonstrated that it meets or exceeds ASTM and AAMA industry standards for air, water, structural, thermal, acoustical and seismic performance. The 400TU Series curtainwall’s enhanced thermal break is located in the tongue area of the back member, and the insulated glass is positioned to the system’s exterior for enhanced resistance to rainwater. In addition to thermal performance, this curtainwall system is tested to meet acoustical performance ratings for Sound Transmission Class (STC) 38 and Outdoor-Indoor Transmission Class (OITC) 32.

Assembled using screw spline or clip joinery, 400TU Series can be specified with either an aluminum or polyamide pressure plate, and as a stick-built system or shop-assembled into “ladders” for field glazing. Verticals can be steel-reinforced for strong windloads. The system’s 6-, 7.5- and 10-inch system depths can accommodate glass or panels of 1- to 1.75-inches thick, and easily integrates with Tubelite’s Therml=Block® entrance systems.

Tubelite’s 400TU Series can be extruded using EcoLuminum™, a high recycled-content aluminum billet composition with eco-friendly, durable finishes. Seven anodized finishes and 20 standard paint colors are available, and upon request, blended and custom colors may be specified.
